DESCRIPTION
Operating in critical conduction mode, the power MOSFET switching loss is reduced and the inductor is fully utilized. The BP2356D integrates a 500V power MOSFET. With few external components, the LED output current can be precisely controlled. The BP2356D utilizes patented floating ground structure. The inductor current is sensed during the whole switching cycle. So it achieves high precision output current control, and excellent line regulation and load regulation. The BP2356D utilizes patented start up technology with HV JFET. So it achieves fast start up, reduce count of external components, and realize smaller form factor. The BP2356D offers rich protection functions to improve the system reliability, including, LED short circuit protection, VCC under voltage protection, CS resistor open circuit protection and cycle by cycle current limit. All the protection functions are autorecovery. The system reliability is further improved by the thermal regulation function. The output current is reduced when the driver is over temperature.
